Summary of advanced supermarket R&D activities conducted under International Energy Agency (IEA) Annex 26.

Summary

Present supermarket refrigeration systems require very large refrigerant charges for their operation and an individual store system can consume as much as 1-1.5 million kWh annually. Several new approaches, such as distributed, secondary loop, low-charge multiplex, and advanced self-contained refrigeration systems, are available that utilize significantly less refrigerant. Analyses show that if properly designed and implemented, these advanced systems can reduce annual energy consumption by over 10% and total equivalent warming impact (TEWI) by as much as 60%. Integration of refrigeration and store HVAC operation is also possible through the use of heat pumps. Integrating the refrigeration and HVAC functions in this manner can potentially reduce combined operating costs by over 10%.
